ULTRA HIGH ENERGY COSMIC RAYS [PDF]
Thinking, Observing and Mining the Universe, 2004 The origin of the cosmic rays at energies in excess of 1020 eV is puzzling the scientific community for several decades now. The mystery adds to the general problem of understanding the nature of the bulk of cosmic rays, that are usually assumed to be accelerated within the Milky Way. Here we summarize the main elements of the observations and propose

Examination of Xmax anisotropy for the next generation Ultra-high energy cosmic rays observations [PDF]
EPJ Web of Conferences, 2023 The estimation of mass composition ultra-high energy cosmic rays is essential to understand their origin and generation mechanism. Recent experiments are expected to discover anisotropy of mass composition in ultra-high energy cosmic rays.

Search for ultra high energy cosmic ray sources
EPJ Web of Conferences, 2017 Earlier we suggested a new method to search for sources and anisotropy of the arrival directions of ultra high energy particles. Here using this method we analyzed the data of the Yakutsk EAS array and found that particle fluxes with energies E < 4.1019 ...

Search for the large-scale cosmic-ray anisotropies using the TA and TALE surface detector arrays [PDF]
EPJ Web of Conferences, 2023 Origins of ultra-high-energy cosmic rays (UHECRs) are still largely unknown. In particular, the “2nd knee” around 1017 eV could be related to a transition of origins from the galactic to extra-galactic sources.
